1. Refer to attached rxn. Write the complete stepwise mechanism for the acid-catalyzed conversion of the enol into its keto form, Compound C.
5. In the alkylation of cyclohexanone, better yields are obtained by first reacting cyclohexanone with an equivalent of lithiumdiisopropylamide in THF and then adding the alkyl halide, rather than mixing cyclohexanone, alkyl halide, and a catalytic amount of sodium ethoxide in ethanol. Explain this observation by pointing out what the problems with the second reaction conditions might be and how the first set of reaction conditions help alleviate the problems.© BrainMass Inc. brainmass.com December 20, 2018, 1:31 am ad1c9bdddf
